SPECIFICATION forming part of Letters Patent No. 568,662, datedSeptember 29, 1896.

Application sled December-4,1895. serai No. 571,047. (No model.)

To @ZZ whom it may concern:

Be it known that I, FRANZ CAZN, a citizen of the United States, residingat Denver, in the county of Arapahoe and State of Colorado, haveinvented certain new and useful Improvements in Crushing-Rolls, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention relates to ore-crushing rolls, and it is the object thereofto provide a pair of rolls longitudinally adjustable in relation to eachother, thus serving to keep the faces of the same exactly opposite andthereby prevent the Wearing of grates in the edges of the said rolls. Toaccomplish this,botl1 rolls may be adjustable in the .direction of theiraxes, or one of the rolls only may be adjustable in this direction.

The device is illustrated in the accompanying drawings, in which- Figurel is a side elevation of the supporting-frame and rolls. Fig. 2 is adetail view of one of the rolls and journals thereof, parts being shownin section. Fig. 3 is a detail view. Fig. ais a'modication in sectionand end elevation. Fig. 5 is a detail view, parts being shown insection.

In the accompanying drawings I have shown an ordinary form ofsupporting-frame Z, in which a pair of rolls a a are mounted, being heldin contact by nests of springs A.

I have shown and described the present invention as applied to only oneroll, but it will be understood the invention may be applied to bothrolls Without departing from the spirit of the invention. Y

In Fig. 2 is shown in detail the roll a, carried by the shaft h, journaled in the trunnionboxes c, provided with a flange which ts Withina corresponding opening in the frame d. This trunnion-box is adj ustablysupported in the trunnion-box frames d, having sliding connectiontherewith, the frame CZ being longitudinally movable in the main frame land guided therein by the bars e, entering recesses in the top andbottom of said frames al.

One end of the shaft Z9 is recessed to form a journal f, and a collar gfits this annular recess, as shown in Fig. 2. A diagonally-extending barc' embraces by its central loop portion the collar g, to which it isconnected by binding-screws h. The bar 'L' is provided at each end withan eye tting over the ends of threaded rods 7s and held theretoadjustably by nuts j. The rods k are rigidly secured at one end to theframe Z, as shown in Fig. 2, or they may be secured to the boxframeitself, as shown in the modiiication Fig. 4.

The adjustment of the ends of the bar t' moves the journal b and therollv carried thereby through the connections described.

Rings N are fixed to the journals l) by suitable binding-screws, and theside edges of these rings abut the edges of the journalboxes, theopposite edges of said boxes bearing against shoulders fm, formed by theenlarged central parts of the hub of the roll. By this arrangement thejournal is prevented from moving independently of the boxes, but carriessaid boxes with it as it is adjusted, thus causing said boxes to slidein the boxframes.

The cross-bar t', as shown in Figs. 3 and 5, may be pivotally secured atone end between the bifurcated ends of the lower rod 7c by the bolt o.

What I claim isl. In combination, the main frame, the trunnion-box framemovable longitudinally thereof, the trunnion -box movable transverselyof said box-frame, and the roll journaled therein, substantially asdescribed.

2. In combination the main frame, the rollers, the shaft yhaving ashoulder m, the trunnion-box frame, the trunnion-box sliding freelytherein in the line of the axis'of said shaft, one end of said boxabutting the shoulder m, and the collar fn. fixed to said shaft andabutting the opposite end of said trunnien-box and means forlongitudinally adjusting and securing in adjustment, said shaft andtrunnion-box.

3. In combination, the'roll, the main frame, the trunnion-box frame, thetrunnion-box movable freely in said box-frame in the line of thelongitudinal axis of said frame, the

roll-shaft, the threaded rods and the bary mounted thereon, and thenuts, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
